Microbeam analysis - electron probe microanalysis - guidelines for qualitative point analysis by wavelength dispersive x - ray spectrometry 微电子束分析.电子探测微观分析.用波长色散x射线光谱测定法定性点分析指南
This and the x - ray spectrum , which exhibits a high concentration of iron atoms relative to oxygen and silicon , convincingly show that the ejecta are the remains of an exploded white dwarf star 这幅图连带x射线光谱（显示出了铁相对氧与硅的高度集中）令人信服地说明，抛出的物质是爆发白矮星的残余。
In third chapter , the article introduced every part of whole spectrum measurement system , such as lpp source , monochromator , detecting system , data acquisition system and vacuum system 第三章是对整个光谱测量系统进行介绍，了解建立起一套极紫外和软x射线光谱测量系统所需要的部件和各部件的工作原理，并对现有的测量系统作了一些改进。
